[Ham-Computers] Computer Clock Problems

OK, my clock problem is solved!

Even though I had replaced the CR2032 battery several times with some spare
batteries I had purchased several years earlier and the voltage on those
batteries was 3.10+ volts, it turned out to be a battery problem.  I finally
broke down and bought a brand new battery, installed it and my clock has
kept time just fine for several weeks now.

So my conclusion is that even if a CR2032 reads an acceptable nominal
voltage, it may not have enough current drain available to power the clock
circuit in the computer.  In the future, I will purchase a NEW battery if I
have another problem like this instead of using perfectly "good" batteries
that I have in my spare battery box......

Just wanted to let others know just in case they run into a similar problem.
That problem sure had me stumped for quite a while......
